Impedance of free space
text:
In electromagnetism, the impedance of free space, Z0, is a physical constant relating the magnitudes of the electric and magnetic fields of electromagnetic radiation travelling through free space. That is, Z 0 = | E | | H |, where |E| is the electric field strength, and |H| is the magnetic field strength. Its presently accepted value is
- Z0 = 376.730313412(59) Ω, where Ω is the ohm, the SI unit of electrical resistance. The impedance of free space is equal to the product of the vacuum permea
